AI-suggested
A fix has been implemented in the Linux kernel to free buffered reports during device destruction. Users should apply the official kernel updates that include this fix. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended remediation.
Description
A memory leak vulnerability in the Linux kernel's HID roccat driver was resolved by ensuring buffered reports are freed when a device is destroyed. Previously, allocations for buffered reports were not released if the device was destroyed before the buffer slots were reused, causing memory leaks.
